The NAACP is protesting President Donald Trump’s proposed visit to the opening of a civil rights museum in Mississippi on Saturday, saying his appearance at the ceremony would be “an affront to the veterans of the civil rights movement.”

“President Trump’s statements and policies regarding the protection and enforcement of civil rights have been abysmal, and his attendance is an affront to the veterans of the civil rights movement,” Derrick Johnson, NAACP president and CEO, said in a statement released this week. “He has created a commission to reinforce voter suppression, refused to denounce white supremacists, and overall, has created a racially hostile climate in this nation.”

“He has created a commission to reinforce voter suppression, refused to denounce white supremacists, and overall, has created a racially hostile climate in this nation,” Johnson added.

Dr. Amos Brown, NAACP board member and San Francisco Branch President, said in the statement: “As a freedom fighter and contemporary of Emmett Till, Trump’s visit is an insult. He has never been a supporter of civil rights or equal opportunity or justice.”
